No April Fool's jokes here: Heathrow's Terminal 4 celebrates its 25th birthday on Friday. Back on April 1, 1986, Prince Charles and his then wife, Princess Diana, arrived at Heathrow via Tube to commemorate the opening.

The terminal, which cost 200 million pounds, was expected to host 8 million travelers a year (in 2009, the terminal carried 5.1 million passengers).

Thanks for posting Nighthawk. Lovely to see Diana again, note how her full attention is on the staff & appears genuinely interested in what they have to say, so different from Waity staring at the camera all the time. Wonder if Ma Manson, was working for BA then?
